Permanent installation of water meters allows easier monitoring of water consumption and greater savings. Although this is not required for LEED, water metering for graywater and rainwater systems is generally included in M&V plans, and monitoring general water use is also worthwhile to verify projected savings. 

The mechanical engineer designs and specifies the appropriate submetering devices, controls, and M&V system. The M&V provider verifies that the M&V program and systems are capable of providing the information required for the credit.

The M&V provider works with the mechanical engineer to verify that all systems are designed to allow metering and submetering. Meters and energy systems must be capable of interfacing with the selected BMS or metering system.

The M&V provider reviews the project design to determine which systems and equipment will be metered, and also determines how many meters will be required. See the guide to commonly metered items in the Documentation Toolkit.

The cost to create an M&V program for Option D, according to IPMVP, is influenced by the following:

size and complexity of ECMs, systems or building;
accuracy of the difference between actual and estimated energy use (a less accurate calculation costs less in man-hours); 
simulation software and its associated complexity;
and the extent and sophistication of submetering.

For new construction, the combined cost of the installed equipment and the first year of monitoring is generally less than 1% of the total project cost for buildings larger than 150,000 ft2—and less than 1.5% for smaller buildings, according to studies.
